Heparin versus DNA: Chiral Preferences in Polyanion Binding to Self-Assembled Multivalent (SAMul) Nanostructures.
This communication presents simple cationic self-assembling multivalent (SAMul) first generation dendrons based on L or D lysine, which form identical nanoscale assemblies in terms of dimensions and charge densities but toward which DNA and heparin exhibit different chiral binding preferences. However, higher generation dendrons with larger hydrophilic head groups are bound identically by these...
متن کاملSelf-assembled multivalent RGD-peptide arrays--morphological control and integrin binding.
We report the synthesis of four different RGD peptide derivatives which spontaneously self-assemble into nanoscale architectures. Depending on the information programmed into the molecular-scale building blocks by organic synthesis, these compounds assemble into different nanoscale morphologies. This process can be fully understood using multiscale modelling which provides predictive insight in...
متن کاملSelf-assembled multivalent carbohydrate ligands.
Materials that display multiple carbohydrate residues have gained much attention due to their potential to inhibit or modulate biological multivalent interactions. These materials can be grouped accordingly to the way they are prepared, as unimolecular or as self-assembled systems. Both systems take advantage of the fact that multivalent interactions have significantly higher binding affinity t...
متن کاملMultivalent bonds in self-assembled bundles of ultrathin gold nanowires.
Ultrathin gold nanowires are unusual colloidal objects that assemble into bundles with line contacts between parallel wires. Each molecule in the contact line interacts with many ligand and solvent molecules. We used X-ray scattering and electron microscopy to study how these interactions control assembly.

This paper reports self-assembled multi-component hybrid hydrogels including a range of nanoscale systems and characterizes the extent to which each component maintains its own unique functionality, demonstrating that multi-functionality can be achieved by simply mixing carefully-chosen constituents. Specifically, the individual components are: (i) pH-activated low-molecular-weight gelator (LMW...
